METALLIC FASTENER.

SPECIFICATION forming part of Letters Patent No. 252,685, dated January 24, 1882.-

Applicntionfilcd December 8,1881. (No model.)

To cllwhomz'tmcy concern:

Beit known that LGEORGE 7. MCGILL, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and usefullmprcvements in MetallicFasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchl as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, making part of this specification, and to the figures and letters ot' reference marked thereon, in which similar letters ofreference indicate corresponding parts.

My invention relates to an improved mode of constructing the metallic fastener for which United States Letters Patent No. 249,850 were issuedto me November 22, 1881, and has for its object the production of a cheap and convenient fastener for binding togethera number of pieces of any kind of textile fabric and attaching marking tickets or tags to the same without the fiber of the materialbound or ticketed being cut or injured by the operation.

Theobjectofmyimprovementistocheapenthe cost of the manufacture of the fastener, which end is secured by using ordinary pins for its penetrating or fastening prongs, and adapting its head to receive and hold the same in proper parallel position at right angles therefrom, thereby vobviating the expense and labor of producing new and s; eci-al machinery to make the shanks or prongs, and economizing considerably on the cost ot' such shanks. A

The fastener is constructed as follows: Its shanks or prongs consist of two or\ more separate pins, A A, ot' ordinary construction, such as shown in Figure 1. These pins are inserted in a metal washer, B, provided with pin-holes b b for their reception.

Figs. 2 and 4 are top or pan views of the washer. Fig. 2shows the washer blanked dat, and Fig. 4t represents it with its center concaved. Fig. 3 is a vertical cross section of Fig. 2, taken on line w a of that figure. Fig. 5 is a similar view, but represents the pin-holes b b pierced or drawn in a manner to produce the tubular sleeves b2 b2 on the under side of the washer to assist in holding the pins in firm vertical position.

Fig. 4 is a vertical cross-section of Fig. 4t taken on the liney 'y of that iigure. The pinholes b b are countersunk so that the top of the heads of the pins will come even with the top ofthe central portion of the washer. The pins A A are inserted in the washer B, as shown in Fio. 6,'which is atop view, in perspective, of the pins and vthe washer so connected. The washer B is now covered by a metal-button cap, C, such as shown in Fig. 7, which represents the cap in reversed position, and the cap is closed upon the washer by an ordinary button-capping machine in the usual manner, thereby locking the washer and cap together and securing the pins A in their pinholes b, as shown'in Fig. S, which is a bottom View, in perspective,of the fastener so constructed, and in Fig. 9, which is a verticalv cross-section of Fig. 8.

Fig. 10 represents a vertical crosssection of the fastener, having its washer B fashioned with a concaved center, as shown in Fig. 4. The object of this form of washer is to cause the closedin flange of the cap to come even oriiushwith the bottom surface ofthe washer, as shown in said Fig. 10.

Fig. 11 is a plan view of a packing-disk, D, which is placed in the sunken center of the washer to pack the pin-heads firmly in their countersunk holes, as shown -in the sectional Fig. l0.

A modification in the construction of the device is shown in the sectional Fig.13, the cap G being shown in reversed position and its center struck up or convexed and provided with pin-holes b b, in which the pins A A are inserted,their heads being covered byacrownpiece, D', correspondingin shape to the .bottom of the cap C, and over the rim or edge of which the flange of the cap is closed down, so as to secure all the paris of the fastener in proper position. Instead of the central part of the reversed cap being concaved, as shown in Fig. l0, it may be pierced by a large center hole, and the shank-pins A inserted in pinholes pierced on each side of the large center hole, and held therein by closing the tiangeof the cap down directly upon their heads,there by producing a fastener with a pierced or ringshaped head, to admit of tags andof such like being readily tied in the same. y

IOO

Fig. 12 is a sideview of the fastener binding together several sheets of material.

In using ordinary pins for the fastenerprongs, as herein described, I first slightly anneal the same,so as to remove 4from themvsoine of their stiffness or elasticity.

I do not claim herein anything shown or described by me in my said United States Letters Patent No. 249,850,0f November 22, 1881.

I have previously made, in accordance with Letters Patent heretofore granted to 1ne, rne tallicfasteners havingtheir penetrating prongs or shanks formed from round wire, pin-pointed and provided with integral heads; and I therefore do not broadly claim herein a fastener having wire Shanks provided with integral heads; but r l What Ido claim, and desire to secure by Letters Patent, is

l. A metallic fastener having its separate shanks formed of round wire with their penetrating ends pin-pointed and their opposite ends pin-headed, 1s shown, and inserted in the countersunkho es b b of the Washer or cap, and secured therein by the washer and cap being connected together,as shown,substantially as and for the purposes described.

2. In combination with the separate pinshanks A, washer B, and cap C, the packingdisk D, inserted between the washer and cap above the piu-heads, substantially as and for the purposes described.

In testimony whereof I hereto affix my signature in the presence of two witnesses.

GEORGE 7. MGGILL.
